A mobile expert system for disease diagnosis of dairy cow was developed for dairy cow farmers and animal husbandmen in Thailand. The application can be used both online and offline modes. Our mobile expert system application was uploaded in Google play store; the user can download application for free. The mobile expert system was designed to be easy and convenient for usage. In this research, we proposed a method of disease diagnosis which consisted of disease screening step and disease diagnosis step. We established the novel model of knowledge representation for inference using gender, age range and significant weight of symptom for disease screening and established the model of uncertain knowledge representation for inference using the significant weight of symptom and the certainty factor of symptom occurred for disease diagnosis. From accuracy measurement results of the disease diagnosis by our expert system which was compared with the veterinarian, it was found that our expert system provided the accuracy of 93.56 %. And the evaluation result of system users' satisfaction with Likert-scale by dairy cow farmers and animal husbandmen were 4.80 and 4.65 respectively.
